Back

A base is a substance that accepts protons (H+) in a solution and has a pH greater than 7.

Front

What is pH?

Back

pH is a scale used to measure the acidity or basicity of a solution, ranging from 0 (strongly acidic) to 14 (strongly basic), with 7 being neutral.

Front

What is a neutral substance?

Back

A neutral substance has a pH of 7, meaning it is neither acidic nor basic. An example is water.

Front
